What does very rarefied air despite high temperature in the thermosphere mean?
Answer and explanation
Correct answer: Heat transfer is not like normal air
The governing concept is the difference between temperature and the amount of matter present. Solar radiation can give the few particles in the thermosphere very high average kinetic energy, producing a high temperature, but the particles are extremely far apart. Consequently, there is little total heat available for ordinary conduction or for warming a person as dense air would. Rain, surface clouds, and soil are not relevant, so option A is correct.
